Atenfold dilution of a sample solution can be obtained by taking

Answer;

1 part sample and 9 papers solder

A tenfold dilution of a sample solution can be obtained by taking 1 part sample and 9 papers solder.

Explanation;Dilution refers to the process of adding additional solvent to a solution to decrease its concentration. The process keeps the amount of solute constant, but increases the amount of solution, thus decreasing the concentration of the solution.Serial dilution is a step wise dilution of a substance in solution. For example, a ten-fold serial dilution could result in the following concentrations: 1 M, 0.1 M, 0.01 M, 0.001 M, and so on, such that the concentration is reduced by a factor of ten in each step.

Answer) by studying proton collisions hope this : )

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.
